Most blown head gaskets can be properly fixed without a mechanic. There is a point where the damage is too great and you will need the expertise of a professional to replace the gasket, but many leaks in a head gasket can be taken care of with one of our products. Head Gasket Repair — p/n 1100.
Common symptoms of a blown head gasket include the following:
- External leaks of coolant from under the exhaust gasket.
- Overheating under the hood.
- Smoke blowing from the exhaust with a white-ish tint.
- Depleted coolant levels with no trace of leakage.
- Bubble formations in the radiator and overflow compartment.
A head gasket sealer works when you pour it into the radiator. You run the car for about 15 to 30 minutes, with the heater and fan on high. A real fix is to replace the head gasket, but this is costly. A head gasket sealer is a good temporary fix.
Usually, a blown head gasket damages the engine because the engine overheats. This is because the damaged gasket can lead to coolant loss, either directly via the gasket damage or from the cylinder pressure increasing the pressure in the cooling system and coolant being pushed out of the overflow.
Since BlueDevil Head Gasket Sealer is not a particulate sealing agent it won't clog or harm any other area of your engine and will create a permanent repair at the leak point allowing you to continue driving your vehicle like normal.
If your head gasket leak has caused this problem you are almost always better off replacing the whole engine as a new head gasket will stop the leak but bearing damage has probably already been done.
There are many stop-leak products that are only designed to be a temporary fix, but not ours. A blown head gasket fix can be as easy as dumping a bottle of sealant in your radiator, and you're good to go. The seal created from our product is as permanent as replacing the head gasket, but with less money and time.
The result can be disastrous as it causes burns which may further start a fire. The issues can be even more complex and can be intimidating if not properly addressed and treated. Hence, it is wise not to drive a car with a blown head gasket. I did, once, for about 10 miles maybe.

A head gasket failure may be caused by an engine overheating one too many times (as a result of a clogged radiator, coolant leak, faulty fan, etc.), but the blown head gasket can also cause the engine to overheat.
Yes a blown head gasket can cause an engine to knock but will usually be a mechanical knock and depends on how the gasket blew. If the engine has been stood for a long time say on the power stroke both valves will be closed and any pressure in the cylinder would have dissipated.
The head gasket may fail in a way that the engine turns over but it won't start or struggles to start. A blown head gasket can keep your car from starting. When you have a blown head gasket, you may have no heat, no white smoke, no start, no check engine light or even no overheating in some cases.
Yes the car should start. A car can start if the head gasket is blown, but it can also not start. It depends on how the gasket blew. Overheating of the engine can cause warpage in the block or head or both.
